@Crystal Stroessner wouldn't we already be seeing much of these in the lending application data or something similar? 

Extra bonus if the destination is up and coming versus already arrived.

Research neighborhoods with growth potential, such as Journal Square in Jersey City, and use data analytics tools to assess profitability.

There is often a range of value that can be supported with market data, but when providing a single point value, they are rarely going to reconcile to either extremes of that range.

If I were you, I would pay to use Airdna data and really look at what other people are making in the different said areas.

We have gotten calls about squeaky closet doors in the extra bedroom.On the other hand I had a tenant for 3 years, I met him when he moved in and again when he moved out.  

I don’t care how extra nice you are to a tenant, it will not matter one bit once you try to enforce rules, raise rent, evict, etc etc.

If taking management in-house costs me even one deal per year, the extra savings disappear.

Albert did cover well the effort (that I claim is comparable to a brrrr with far lower return) and timeline (except sometimes the timeline exceeds 9 months, but it probably should not if the jurisdiction does its part and you have good contractors).NAR provided Nov 2021 data for many large cities of average sale of properties with an ADU versus without an ADU.  

Data, comps, and expert insights give us facts.
